I started to work with CryEngine Sandbox eight years ago. (damn, already 9 years?) I also work with Game Maker.
Maybe you ask why I have posted image of this mostly empty place.
Using LODs and billboard LODs I managed to double the view distance. Originally, you couldn't see from one end to a second end of the square. As you can see now, even the boulevard behind it can be seen.
Another good news is: I have managed to think out a way of loading ground textures, which is effective and even quick. Until now, loadings of ground textures meant ~1-2 second freezes and it didn't even work properly. Now all of those problems seem to be gone!
